深埋引水隧洞岩爆预测及防治措施

岩爆作为深埋地下工程在开挖后常见的一种地质灾害，极大地威胁着施工人员和设备的安全。在全面分析岩爆影响因素的基础上，从众多岩爆预测判据中，有针对性地选取了Rb／σ1判据、陶振字判据和卢森判据对某深埋引水隧洞进行了岩爆预测，结果表明整个工程以中等岩爆为主，局部洞段会发生强岩爆，同时针对不同岩爆等级提出了合理的防治措施。

Study on Rockburst Prediction and Prevention of Long deeply Burial Water Division Tunnel

Rockburst as a kind of familiar geological hazard in deep and over-length tunnel, the safety of constructions and equipments are threatened by it. On the basis of analyzing the factors of rockburst combined with the long deeply burial water division tunneling engineering, the Rb/σ1 criterion, Taozhenyu criterion and luessen criterion are used to predict rockbrust and its grades. Finally, based on the practical situation, some prevention methods is suggested.
